Absolute programming

[Joels]

My company likes to mix absolute and incremental Cnc programming, does any one know of a web page or iPhone app that will let me plug in some numbers and get the result? For example we have two lines at 90 deg and I need to put say a .250 radius on the intersection. Or does anyone have a good idea to do this ?

Mixing ABS & INC is great for pencil cam but if you're using any other cam system you're just wasting time and money.

One of our Customers work 100% in inc only....they like it because back in the late 70's when they first got a cnc, it would only run inc.

So they stuck with it and now have multi million pound fms cells running on it.

And any 'new' operators go WTF???

And their cam company (not mcam) also said WTF???

If it's just the arc you need to be incremental, try changing arcs in the control def to 'Delta start to Center'. Mastercam should post the arc in inc format.

KFrey,

 

This is actually false. With that setting the I and J are incremental distances but the X and Y coordinates are absolute.

Sorry, it works on my Numeripath post, but come to think of it, the post was modified.

Not an app or web page, but I'd recommend running your code through NCPlot to see what it will do. http://www.ncplot.com/

They have to adjust the machines for taper on the part, We machine alot of Titanium and they dont like us to go to Mastercam to fix programs. They want us to fix it on the machines.
